WebBy the definition of a derivative this is the limit as h goes to 0 of: (g (x+h) - g (x))/h = (2f (x+h) - 2f (x))/h = 2 (f (x+h) - f (x))/h Now remember that we can take a constant multiple out of … Webwhich is just the derivative of one scalar with respect to another. The rst thing to do is to write down the formula for computing ~y 3 so we can take its derivative. From the de nition of matrix-vector multiplication, the value ~y 3 is computed by taking the dot product between the 3rd row of W and the vector ~x: ~y 3 = XD j=1 W 3;j ~x j: (2)

An antiderivative of a function f is a function whose derivative is f. In other words, F is an antiderivative of f if F' = f. To find an antiderivative for a function f, we can often reverse the process of differentiation. For example, if f = x4, then an antiderivative of f is F = x5, which can be found by reversing the power rule. lai yoon kee
